The prompt
Create a highly detailed, accurate 3D CAD-style gear model suitable for engineering visualization, mechanical design, and 3D printing. Gear type: [Spur / Helical / Bevel / Worm / Rack & Pinion / Herringbone / Internal / Planetary / Custom] Design requirements: - Precisely modeled gear teeth with uniform spacing and accurate tooth profiles - Clearly defined pitch circle, root circle, and outside diameter - Realistic tooth geometry with proper involute profile where applicable - Accurate central bore with optional keyway - Symmetrical and mechanically functional construction - Smooth fillets and chamfers on sharp edges - Realistic proportions and engineering dimensions - High-resolution geometry with clean surfaces - No broken, overlapping, or distorted teeth - Show the complete gear from multiple angles - Include front, side, top, and isometric views - Add a sectional/cutaway view if useful to show internal geometry Material appearance: Use realistic engineering material such as hardened steel, stainless steel, aluminum, or brass. Add physically realistic metallic surface properties, subtle reflections, and fine machining details. Engineering details: Include labels or dimensions for: - Number of teeth - Module / diametral pitch - Pressure angle - Pitch diameter - Outside diameter - Root diameter - Face width - Bore diameter - Keyway dimensions - Helix angle where applicable Presentation: Place the gear on a clean neutral engineering background. Use professional CAD visualization, realistic studio lighting, sharp edges, accurate shadows, and high-quality 3D rendering. Output: Create a mechanically believable, dimensionally consistent 3D gear model, optimized for engineering presentation and potential CAD/3D-printing reference. Avoid unnecessary decorative elements.
